You can run the following command from a Windows command prompt to remove an app for all users that will login to the PC.  This should be done before deploying the PC and will not remove the apps for users that have already logged in. This command removes Solitaire as an example.
 
powershell -command "Get-AppxPackage -AllUsers -Name *solitaire* | Remove-AppxPackage -ErrorAction SilentlyContinue"
 
You can also run a similar command as the user to remove the app for that user. (Just remove the "-Allusers" string and add the "-windowstyle hidden" string)
 
powershell –windowstyle hidden -command "Get-AppxPackage -Name *solitaire* | Remove-AppxPackage -ErrorAction SilentlyContinue"
 
You can include commands for several different apps into a single script and run that on the PC or as the user at login.
